Add a TTCN3 module for IPA protocol testing
This new module allows us to test IPA code in libosmocore
and libosmo-netif. Currently only one test is implemented,
which sends a chopped IPA ping message and expects to receive
an IPA pong.
The system under test is any IPA speaker on any TCP port.
Any test suite may call parametrized functions to create
an IPA testing component and run a particular test.
So far, one such test has been added to the BSC_Tests suite.
